Một xưởng dệt thảm được giao làm một số thảm trong 30 ngày. Thực tế xưởng dệt đã tăng năng xuất lên 25% nên sau 25ngay không những đã làm xong số thảm mà còn làm thêm được 20 chiếc nữa. Tính số lượng thảm mà xưởng đã dệt trong 25 ngày

Answers

Answer 1
Answer:

Gọi số tấm thảm xưởng dệt dệt theo dự định là x ( tấm, x >0 )

⇒ số tấm thảm xưởng dệt dệt trong 1 ngày theo dự định x/30 (tấm)

xưởng dệt dệt đc số tấm thảm trong thực tế là x/20 (tấm)

⇒số tấm thảm xưởng dệt dệt trong 1 ngày thực tế là x+20/25 (tấm)

Vì năng suất tăng 25% nên số tấm thảm dệt được trong 1 ngày thực tế sẽ bằng 125% số tấm thảm dệt đc trong 1 ngày theo dự định nên ta có PT : x+20/25=125% * x/30

me lười làm khúc dưới quá nên tự xử nha.

Which describes how the parent function, f(x) = |x|, is transformed to show the function f(x) = 0.1|x – 3|? A.It is wider and shifted 3 units to the left.
b. It is wider and shifted 3 units to the right.
c. It is narrower and shifted 3 units to the left.
d It is narrower and shifted 3 units to the right.

Answers

Transformation involves changing the position of a function.

The true statement is: (b) It is wider and shifted 3 units to the right.

The function is given as:

\mathbf{f(x) = |x|}

First, the function is translated right by 3 units.

So, we have:

\mathbf{f'(x) = |x - 3|}

Next, the function is enlarged horizontally by a factor of 0.1.

So, we have:

\mathbf{f

The above highlights mean that:

\mathbf{f will be wider than \mathbf{f(x) = |x|}

Hence, the correct option is (b)

You cannot bisect an angle using paper folding constructions True or False

Answers

Answer:

The given statement:

You cannot bisect an angle using paper folding constructions is a False Statement.

Step-by-step explanation:

The construction of a angle bisector with the help of paper folding is done by:

  • Draw a angle ACB on a piece of paper such that the ray CB lie on the base.
  • Fold the paper in such a way that ray AC falls along the ray CB.
  • draw the line along the crease that is formed on the paper starting from point C.
  • So, the ray so formed is the angle bisector of the angle ACB.

Answers

Answer:

2^{(18)/(11)}

Step-by-step explanation:

The given expression is

\sqrt[11]{y^2z^4}

The exponent property\sqrt[n]{x^ay^b}=x^(a/n)y^(b/n)

Applying this exponent property, we have

\sqrt[11]{y^2z^4}\n\n=y^(2/11)z^(4/11)

Now, the given numeric values are x = 9, y= 8, and z= 16

On substituting these values in the simplified expression, we get

(2)^(2/11)(16)^(4/11)

This can be further simplified by writing 16=2^4

(2)^(2/11)(2^4)^(4/11)\n\n(2)^(2/11)(2)^(16/11)

Now, applying the product rule of exponent: x^a\cdot x^b=x^(a+b)

(2)^(2/11+16/11)\n\n=2^{(18)/(11)}

Jackie is making flower arrangements. She has 2 roses and 4 daisies. If Jackie wants to make all the arrangements identical and have no flowers left over, what is the greatest number of flower arrangements she can make?help<3

Answers

Let's explore possible case scenarios.

---------------------

Case A) Each person gets a rose and a daisy (2 flowers per person)

In this case, Jackie can make 2 such arrangements because she has 2 roses. We have 2 left over daisies.

---------------------

Case B) Each person gets a rose only (1 flower per person)

Only two arrangements are possible for the same reason as case A. In this situation, we have 4 left over daisies.

----------------------

Case C) Each person gets a daisy only (1 flower per person)

We have 4 arrangements possible because we have 4 daisies. The left over flowers are the 2 roses.

-----------------------

Case D) Each person gets 2 roses

Only one such arrangement is possible, so this only applies to one person really. You can say that 2/2 = 1. We have 4 left over daisies in this case.

-----------------------

Case E) Each person gets 2 daisies

Since 4/2 = 2, this means we can make 2 arrangements. There are 2 left over roses.

------------------------

Case F) Each person gets 2 daisies and 1 rose

We can see that 4/2 = 2 and 2/2 = 1, meaning that we can make at most 2 arrangements here. There are no leftovers. In contrast, the other cases do have leftovers of some kind.

------------------------

In short, you can do trial and error to see which case works to fit the conditions your teacher set. Case F is what we go for to have each flower bouquet consist of 2 daisies and 1 rose. We'll get 2 bouquets possible. Notice how cases A through E have at least one left over flower (either of one kind or both types), while case F has no leftovers.
